Answer:
3.6 centimeters in 4 seconds.
Step-by-step explanation:
Given, 2.7 centimeters in 3 seconds. x centimeters in 4 seconds.
We will solve this problem by unitary method.
since in 3 seconds = 2.7 centimeters
therefore, in 1 second =
Therefore, in 4 seconds = × 4
=
= 3.6 centimeters
3.6 centimeters in 4 seconds.
130, - 12, 56.1, 11.2
these are all arithmetic sequences with n th term formula
=
+ (n - 1 )d
where d is the common difference and the first term
(1)
d = 10 - 4 = 4 - (- 2 ) = 6 and = - 14
= - 14 + (24 × 6) = - 14 + 144 = 130
(2)
d = 14 - 16 = 16 - 18 = - 2 and = 22
= 22 + (17 × - 2 ) = 22 - 34 = - 12
(3)
= 2.2 + (49 × 1.1) = 2.2 + 53.9 = 56.1
(4)
= - 4.2 + (11 × 1.4 ) = - 4.2 + 15.4 = 11.2
Answer:
Step-by-step explanation:
From the given question,
a). m∠WAX = 60°
If m(arc WX) = 100°
Then by theorem,
Angle formed between the chords in a circle, measures the half of the sum of intercepted arcs.
m(∠WAX) =
60° =
120 = 100 + arc YZ
120 - 100 = arc YZ
m(arc YZ) = 20°
b). m(arc WX + arc YZ) = 2(60°)
m(arc WX + arc YZ) = 120°
